2017 Map of Ralston

About this map

The Shoshone River valley defines the central landscape of this Park County region, where the high desert terrain is transformed by an extensive irrigation network. The Garland Canal and Frannie Canal dominate the northern half of the map, supporting the agricultural communities of Ralston and the southern edge of Powell. This complex system of laterals, including Lateral R and Lateral S, feeds the cultivated fields of Powell Flats and Ralston Flats, creating a sharp contrast with the arid, dissected topography to the south. In this southern portion, the land rises into a series of drainages and seasonal watercourses such as Willwood Draw, Peerless Coulee, and Roan Wash. The transition from the structured grid of the irrigated valley to the natural contours of the Big Horn Basin provides a clear look at the intersection of water engineering and local settlement patterns.
